SYNTAX
call atomic_and(atom, value [, stat])
DESCRIPTION
atomic_and(atom, value) atomically defines ATOM with the bitwise AND between the values of ATOM and VALUE. When STAT is present and the invocation was successful, it is assigned the value 0. If it is present and the invocation has failed, it is assigned a positive value; in particular, for a coindexed ATOM, if the remote image has stopped, it is assigned the value of iso_fortran_env’s stat_stopped_image and if the remote image has failed, the value stat_failed_image.
ARGUMENTS
ATOM - Scalar coarray or coindexed variable of integer type with atomic_int_kind kind. VALUE - Scalar of the same type as ATOM. If the kind is different, the value is converted to the kind of ATOM. STAT - (optional) Scalar default-kind integer variable.
EXAMPLE
Sample program:
program demo_atomic_and use iso_fortran_env integer(atomic_int_kind) :: atom[*] call atomic_and(atom[1], int(b’10100011101’)) end program demo_atomic_and
